I'm interested in the UI-related stack exchange. Apparently, I'm not allowed to commit to it now that it's in private beta.
I'd like to be able to be notified when it goes into public beta, but that's not my main point. If I can't commit now, you should say that, rather than providing a link at the bottom of the page that does nothing!

I totally agree. When clicking on the “Commit to this proposal!” link I initially thought something was broken. Also, it's not a good practice to use Javascript within the href attribute, use proper URLs instead, so your interface degrades unobtrusively.
